No, you don't understand what you are saying at all. Also, you evaded the simple question that would have proved you wrong from what you had yourself said earlier.
Anyway, with regard to what you said, you yourself conceded that Trent teaches perfect contrition with respect to penance. Can you prove this from the deposit of revelation? From the Fathers? I doubt it.
But at least once Trent had affirmed it, it would henceforth be held unanimously by theologians that the Church had closed the question.
This is what St.Alphonsus and St.Robert Bellarmine, two illustrious Doctors, Saints and theologians par excellence, along with all other theologians, also say with respect to Baptism of desire, after Trent, at least, there is no more question. St.Alphonsus says it must be held as de fide on account of Trent, for the truth of baptism of desire is equally certain as the truth of the necessity of baptism.
Show me a single theologian, let alone, Saint or Doctor of the Church who has treated the matter as if it were open to dispute at least after Trent. It is not.
Remember the Church sometimes leaves some doctrines, when it is not yet evident that they belong to the deposit of faith, open for dispute, in order that a more coherent case may be eventually made for its dogmatic definition. This was so for example with the dogma of the Immaculate Conception, where Scotus' theological reflections were most useful, and with some specifics of Papal Infallibility.
Laymen, who belong only to the Church taught should only ever have the attitude of students learning with all humility and docility toward the teaching Church.
The teaching Church are assisted by theologians in communicating the teaching of the faith and the Church to us. So what the constant teaching of theologians tells us is what questions the Church has definitively settled.
It is now, at least after Trent as St.Alphonsus says, no more lawful now to call into question baptism of desire than it is to call into question any of the other doctrines of the faith or those mentioned above. Show me a single learned authority to the contrary.
